hi guys
this is my first post in this site and i hope that you can help me.

i have a th350 with a 3000stall and a full manual reverse valve body.
i'm know trying to figure how to do the installing for the v/b. there is the instructions.
Illustration 1

Note: From 1967-1968, 1970-1979 and 1980 the Turbo 350 transmission was manufactured with different case configurations, Your case may not look exactly like the illustration shows, but the functions of the transmission are the same.
Remove the intermediate servo piston, washer, spring seat and apply spring. Note: These components can be discarded as they are no longer used.
(See Illustration 1) Drill and tap a hole using an 11/32" drill in the area shown in Illustration 1. A second hole must be drilled and tapped In the second gear accumulator area. Plug both holes using 1/8" allen head plugs included in kit.

where is the second gear accumulator area ?
do i need to apply a spring after removing the parts?

help me understand this
thanx in advance

 

anyone guys?
